JOHN V. WHITBECK, OF CLEVELAND, OHIO, ASSIGNOR TO THE CHANDLER MOTOR GAR COMPANY, OF CLEVELAND, OHIO, A. CORPORATION OF OHIO.

COMBINED TRAP AND GASOLENE-STRAINER.

Specification of Letters Patent.

Patented Jan. 20, Mild.

Application filed May 2, 1914. Serial No. 835,807.

To all whom it may concern:

Be it known that 1, JOHN V. Wnrrnncn, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Combined Traps and Gasolene-Strainers, of which the following is a specification.

My invention relates to a valve controlled coi'nbined gasolone trap and strainer and one of the objects of the invention is to provide a simplified form of trap and strainer which can be made gasolene tight without the necessity of refined accuracy in machining the interfitting parts.

Another object of the invention is to provide a device of the character described all of the bores of which are easily drilled and can be conveniently cleaned when the several parts are demounted.

A further object is to provide a simple compact trap and strainer of relatively few parts, the strainer of which may be qui kly replaced without removing the device rom its position on the gasolene supply pipe.

Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanying drawings and in part will be more fully set forth 1n the followin particular description of one form of vmecianism embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

Referring to the accompanying drawings:

Figure 1 is a central vertical sectional View of a referred embodiment of my invention ta (on on the line 1-1 of Figs. 2 and 3;

Fig. 2 is a view in elevation of one side of the device shown in Fig. 1; and

Fig. 3 is a plan view of the device shown in Fig. 1.

As shown in the particular construction illustrated in the drawings there is shown a cup shaped shell 1 comprising a settling chamber, which has a reduced and downwardly tapered bottom 2 terminatin in an outlet 3, within which is tapped a dram cock t by means of which water and sediment can be discharged from the shell. The up or end of the shell is exteriorly screw threaded and telescopes into the threaded flange 5 depending from the cap 6 which closes the open top of the settling chamber. The cap has an openin 7 extending through the center thereo into the settling chamber, the inner portion of which opening is frusto-conical, with the larger end inward, to form a valve seat, facing the chamber for the similarly shaped cone plug valve 8 which controls the supply of gasolene to the trap. The outer end of the opening is reduced to form ashouldered stop 9 for limiting the outward movement of the valve. The valve includes a stem 10 which projects through the reduced portion of the opening and which has an operating handle 11 fixed' thereto. To look the valve in place, a perlieu of the stem exteriorly of the cap is formed noncircular in cross-section, which portion is engaged by a notched lock washer 12 resting on top of the cap to hold the valve in its set positions, either opened or closed, as desired.

A coiled spring 13 encircles the stem and bears on the washer and handle to maintain the valve in "asolene tight engagement with its sent. This spring may be made as long as desired and should have a tension sufficient to overcome/any leakage due to small inaccuracies of the fit between the valve and its seat. The valve has an inverted l..-shaped passageway therein, one arm 14 of which is axially disposed in the valve and opens into the settling chamber and the other arm 18 of which is radially disposed and is adapted to be moved by the rotation of the valve into position to form a continuation of the inlet ll) which extends through the cap from the outside thereof to the frusto-conical portion of the opening 7. The cap also has an outlet 17 on the side thereof opposite the inlet lending directly from the settling chamber. The outer ends of the inlet and outlet are preferably tapped to receive the gasolene pipe as is usual with devices of this character.

A strainer 18 of suitable material, such as wire gauze, is fastened in position between the top of the shell and an annular shoulder 19 formed by the flange 5 and underside of the cap. The strainer has a central opening fitted about the lower portion of the valve, which is reduced for this purpose.

lln order to support the trap independently of the gasolene pipe the cap has a lug 20 fixed to the top thereof which may include a screw 21 by means of which the trap is suspended from a suitable support.

In operation with the parts in the position shown in Fig. 1, the notch lock washer is moved into an unlocking position and the valve rotated to place the settling chamber in communication with the supply of gasolene through the inlet. The gasolene will flow into the trap precipitating the heavy water and sediment as is usual with devices of this character.

The light oil will fill the chamber and the top portlon thereof will flow past the screen and out of the device through the outlet. When desired, the drain cock may be open to empty the settling chamber of its foreign matter and when the strainer becomes cloggedthe' shell is unscrewed and a new strainer inserted on its seat.

By means of a device of this character, the trap and shut-oif cock is combined in one article and as but one passageway is formed in the valve, this valve may be made relatively small thus minimizing the leaking area between the valve and its seat and minimizing the number of fluid openings which pass through this valve seat. The outlet is open at all times to permit a direct and free flow of the gasolene from the trap and is independent of the valve. It is noted that any irregular grinding or wearing of the valve might possibly cause a leak e from the inlet 16 into the settling chamber but there would be little if any tendency to leak to the outer side of the device due to the fact that one source of possible leakage, i. e. the outlet, is spaced from the valve and further the bearing between the valve and its seat is relatively long.

, All of the parts may be cast and the several passageways may be straight drilled thus providing an easy cleaning of the several passageways when the parts are demounted.

As there are no tubes or other obstruction in the settling chamber this chamber has the largest capacity possible with the desirable small size of the device.

While I have shown and described, and

have pointed out in the annexed claims, certain novel features of my invention, it will be understood that various omissions, substitutions and chan es in the form and details of the device i lustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.

Having thus described my invention, I claim:

1. In a device of the class described, a cap having a recess on one side, a valve engaging member fitted in said recess, said cap having an opening extending therethrough, the inner portion of said opening being frusto-conical with the lower end adjacent the recess, a cone plug valve fitted in the frusto-conical portion of said opening, said plug having a reduced extension rotatably mounted in said valve engaging member, and having a passageway extending through said extension, said cap provided with a passageway designed to open from said passageway through the valve.

2. In a device of the class described, a cap having a recess on one side, a valve engaging member fitted in said recess, said cap having an opening extending therethrough, the inner portion of said opening being frusto-conical with the lower end adjacent the recess, a cone plug valve fitted in the frusto-conical portion of said opening, said plug having a reduced extension rotatably mounted in said valve engaging member, and having a passageway extending through said extension, said cap provided with a passageway designed to open from said passageway through the valve, said valve provided with a stem extending exteriorly of the cap and a notched lock washer adapted to hold the valve in its set position.

Signed at Cleveland, in the county of Cuyahoga and State of Ohio this 27th day of April, A. D. 1914.
